| Administrative History | One of the annotations on the other draft cites the work of James Heywood, 1837. Probably used as part of the research for the second edition of Greenough's Geological Map of England & Wales' (1840).
Note: the base map of this draft is from the first edition, but Greenough has scraped off the tell-tale labels and fossils in the stratigraphical column on the left. On this copy, Greenough has emphasised the location of rivers. |
